Catalysts for the Selective Oxidation of Methanol

Catalysts for the Selective Oxidation of Methanol

In industry, one of the main catalysts typically employed for the selective oxidation of methanol to formaldehyde is a multi-component oxide containing both bulk Fe2(MoO4)3 and excess MoO3. It is thought that the excess MoO3 primarily acts to replace any molybdenum lost through sublimation at elevated temperatures, therefore preventing the formation of an unselective Fe2O3 phase. With both oxid...

Effects of the Solvent and Calcination Temperature on LaFeO3 Catalysts for Methanol Oxidation

In this work, two types of solvents ethanol or water were used in preparation of the LaFeO3 catalysts by citrate sol gel method. The obtained samples were subjected to various calcination temperatures in order to study the catalytic activity and stability for methanol electro-oxidation by XRD, cyclic voltammetry and chronoamperometry. The crystallinity of the LaFeO3 ph...

Vanadium-phosphate Catalysts for Methanol Production by Selective Oxidation of Methane

Selective oxidation of methanol to dimethoxymethane over bifunctional VO(x)/TS-1 catalysts.

This communication describes the design of bifunctional VO(x)/TS-1 catalysts with enhanced redox and acidic character via doping SO(4)(2-) and PO(4)(3-) for selective oxidation of methanol to dimethoxymethane. Redox sites enable the production of formaldehyde, while acidic sites favor the condensation of formaldehyde to DMM.
